RC tank

Often made cylindrical structure. Tank top cover, wall panels and floor is composed of three parts. Generally used for storage of heavy hydrocarbons. This type of tank, steel, good durability, low maintenance cost and the advantages of oil loss, but the construction process more, longer duration. Also semi-underground and underground concrete oil tank fire performance, the advantages of tank space small, small wall temperature difference. When the oil tank capacity is larger, the use of prestressed concrete tanks, Shi Jiahuan pre-stress, their methods are:

① electric tension method;

II Jack tension method;

③ coiling machine winding along the high walls and wire (the wire-wound prestressed).
